"The thicker the floor, the better the foot feel. Is it more insulated?" "Is it special for floor heating to use aluminum foil foam pads?" Get rid of the mists and mists, get out of the misunderstanding, and make consumers buy and use floor heating floors openly. Therefore, the expert group of our association summarized the top ten misleading in the current consumption of floor heating floors as a warning:
"the thicker the floor, the better the foot feel, the more heat preservation?" "Is it special for floor heating to use aluminum foil foam pads?" To get rid of the mystery and get out of the misunderstanding, so that consumers can clearly choose and use floor heating floors. Therefore, the expert group of our association summarized the current top ten misleading consumption of floor heating floors as a warning:
1 "Are all floors suitable for floor heating?"
"can your floor be used as floor heating floor?" The shopping guide answered, "absolutely no problem, geothermal special floor." Almost every floor seller answered in such a very positive way, and also took out user examples, and some also took out test reports, so consumers felt that "all floors should be floor heating floors." As we all know, it is necessary to meet four factors for floor heating: floor heating conductivity, dimensional stability, anti pollution and environmental protection, and durability. The flooring industry is formulating flooring standards to quantify the four elements, and formulating quality inspection specifications for flooring laying and warranty period to quantify the technical indicators of laying and maintenance
2. "Is the name of special geothermal floor right?"
in the current floor circulation market, there are not only a wide variety of floors used for ground heating, but also their names are more disordered: such as "anti heat floor", "anti geothermal floor", "ground anti heat floor", etc. the most popular ones are "heating floor", "ground heating floor", "heat-resistant floor", "geothermal floor", "special geothermal floor", etc. we believe that some names are unscientific, and some names seem to be inappropriate, especially the ground radiant heating system, At the initial stage of vigorous development, the name must be standardized. It should be called "floor heating" and its definition should be: it is suitable for the wooden floor laid by the ground radiant heating system, and transfers heat to the room through the board
3. "Is the thicker the floor, the more insulated?"
the thickness of wood floor is the factor that determines whether its feet feel comfortable, so many consumers require a thickness of 15-18mm when purchasing floors, especially solid wood, multi-layer solid wood or bamboo floors. Therefore, when purchasing floor heating, they also use this method to choose, but everyone knows that wood is a bad conductor. Usually, the thermal conductivity of wood material is between 0.17-0.34, while water is 0.5. If the floor is too thick, it is more unfavorable for heat to be transmitted to the board through the floor, and it is consumed in the transmission process. As for insulation, the temperature difference between the top and bottom of the floor is very large, which will inevitably lead to great deformation of the floor. "Thermal expansion and cold contraction" and "wet expansion and dry contraction" will cause the floor to scoop, twist, bend and crack, and the dimensional stability can not be guaranteed
4. "Is the specification of geothermal heating floor too wide?"
now consumers buy solid wood flooring for comfort and to show their identity. Therefore, when purchasing, we often choose those floors with larger specifications, especially in the width direction, some of which can reach 180mm. In the daily floor paving, experts do not recommend users to choose such a width, so as to avoid the seam separation due to the wet expansion and dry contraction of the floor. Moreover, when the floor is heated, the seam separation of the floor is more likely to occur due to the faster moisture distribution. Therefore, experts suggest that consumers should try not to choose floors with too large specifications when choosing geothermal heating floors
5. "Is the floor mat with aluminum film special for floor heating?"
this is the most typical misleading. Practice has long proved that in the ground radiation heating system, the heat transfer is mainly radiation, followed by convection, and finally conduction. If the heat dissipation ground is covered with aluminum foil to form anti radiation, under the condition of maintaining the same surface temperature of the ground heating, the thermal resistance of the foam pad with aluminum film is large, while the thermal resistance of the ordinary foam pad is small. Obviously, the heat conduction effect of ordinary foam pad is better than that of foam pad with aluminum film, which is more conducive to heat conduction from the floor to the room. Therefore, when purchasing floor heating, users should choose ordinary foam cushion or material cushion with small thermal resistance, good moisture resistance and corrosion resistance to lay
6. "Can you add plywood or Blockboard under the floor?"
first of all, laying plywood or Blockboard under the geothermal heating floor is not conducive to heat conduction, which virtually increases the loss of heat in the conduction process and increases the heating cost of the geothermal heating system
secondly, if the quality of these selected boards is not up to standard, it will also lead to the indoor free formaldehyde content exceeding the standard, or because its moisture content is not up to standard, the moisture is absorbed by the floor after laying, resulting in tile deformation, arching and other phenomena on the floor. In addition, this base plate has more disadvantages than benefits, which is really self defeating and adding to the snake! It is not allowed to lay bedding under the floor
7. "Can we only manage by floating?"
due to the special structure of geothermal heating system, the cement floor cannot be nailed when paving the floor. Therefore, for a long time, most of the geothermal floor paving only recognizes the suspension paving method. In fact, with the continuous progress of science and technology, there are two other paving methods: floor bonding method and keel paving method. Recently, a kind of quick installation keel has appeared in the market. This kind of keel is paved without nails. The keel can be directly fixed on the cement ground with glue, and then the floor can be fixed on the keel through the snap on the keel. This can not only increase the foot feel of the floor, but also, because there is space between the keels, the air can convection up and down the floor, which is conducive to the circulation and convection of heat, and make the floor heated more evenly, with less deformation and higher thermal efficiency of the room. This is the preferred laying method of the current value
8. After the floor is paved, the floor temperature rise test will not be carried out.
after the geothermal heating floor is installed, in addition to the routine acceptance, the most important thing is to carry out the temperature rise acceptance of the floor. After the completion of floor laying or heating in winter, the ground heating system should be heated slowly for the first time. When the foundation ground temperature rises to 25 ℃, the constant temperature should be kept for 12-24 hours. After that, slowly raise the temperature at 1 ℃/h to the required indoor temperature (14-22 ℃), the temperature should not be too high, and the temperature of the wooden floor should be ≤ 28 ℃. In a short time, the limit temperature is ≤ 32 ℃, the higher the temperature is, the greater the heat loss is, the shorter the service life of the thermal system is, and the hidden danger is easy to occur, and the floor is easy to produce ladle, twist, bend, crack and other deformation
9. After the floor is paved, there is no environmental protection acceptance
because most of the floors used as the floor heating system are composite floors (solid wood composite, reinforced and bamboo wood floors), there is a problem of formaldehyde emission itself, and when they are used as geothermal floors, after heating, the formaldehyde emission is even more serious. Therefore, after the geothermal heating floor is paved, we must do environmental protection acceptance to ensure that the release of free formaldehyde meets the standard (the national standard is 1.5mg/l). In order to make the floor work normally, we must do two things when buying: ① environmental inspection should be done before the floor is paved. Generally, the inspection is free, and the treatment should be charged. After the floor is paved, the inspection should be done for environmental protection acceptance. ② The environmental protection indicators of flooring and accessories must meet the standards. Don't buy cheap goods that are not environmentally friendly at heavy prices, otherwise there will be endless trouble
10. Placing legless combination furniture or carpets on the floor destroys the heat dissipation surface of the floor
with the continuous improvement of modern people's living standards, people are increasingly pursuing personalization for home decoration, so many personalized assembled furniture came into being, which can be assembled arbitrarily according to the owner's preferences. However, these furniture are often legless furniture with the ground floor in direct contact. If the geothermal heating floor is paved indoors, its furniture and carpet are directly covered with the floor in a large area, which will make the floor here unable to dissipate heat, and excessive concentration will lead to uneven heating of the floor, resulting in deformation of the floor here, waste of heat energy, and low room temperature
